Note: High Sierra supports only CPUs with SSE4 support, example: my Q9400 or my Q8200 working with Sierra. Core2Duo E7200 / Core2Quad Q8200 or higher works as well. See CPU-X.app for your CPU !!!

For a direct update from 10.12 to 10.13, you first install the latest version of Clover.Copy your Kext's from Clover/kexts/10.12 to /other.Note new BIOS data and firmware data in Clover's config.plist in SMBIOS. For more information read on.

With High Sierra, there is a black screen with the HD5450, because C2D and C2Q have no Injector iGPU. Since High Sierra, the HD5450 needs a rollback from Sierra.
WhateverGreen.kext + Lilu.kext does not work with LegacyBios, unfortunately.

Save in advance the following Kext's from your Sierra installation from /System/Library/Extensions:

The current original apfs.efi can be found after each install or update in usr/standalone/i386/ (use ShowAllFiles!).
The new file system is only for SSDs. HDDs continue to work with HFS+.

copy the apfs.efi to EFI/Clover/drivers64/

8. Now High Sierra install on your HDD or SSD (Partitions with Guid scheme)

The installation, even with subsequent updates, can take place in several steps.
My experiences:
APFS two steps
HFS+ one step

8.1 With the HD5450 there is a black screen the first time after the install.
I take the SSD out of the Dell and connect it to another Mac.
Here I am using the app "EasyKext Pro" and doing the rollback from the backup (step 6 above - AMDRadeonX3000.kext, AMDRadeonX3000GLDriver.bundle, IOAccelerator2D.plugin and IOAcceleratorFamily2.kext from Sierra 10.12.6).
Reinstall SSD in the Dell and now we get a picture in High Sierra.

If running onboard Intel HD 3000 graphics, DP works OOB. However, VGA does not. It does work with the following patch, however it should be noted that VGA only works once you are fully booted and manually searched for displays in the display control panel. In my case this breaks sleep.

However, it is also possible to use the onboard graphics and a GPU card at the same time. For this you'll need to change the video settings in the BIOS and it should be noted that this only works if there actually is a monitor (or a dummy) present on both outputs upon booting. In my case the Optiplex POSTS to the onboard graphics, but once macOS is fully booted the graphics card comes up too.

Good morning, everyone, I'm sorry if I was wrong in choosing the topic but I need help.I have found it extremely difficult to mount a Hackintosh in my acer.Setup;I5 2430m 2.4

If anyone can help me, I'll be grateful.
Installations without success, but with the system already installed in ACER;
